freebsd stable - Sep 2012 - [PATCH] Locking for adv(4), adw(4), aha(4), ahb(4), aic(4), and bt(4)

I have patches to add locking to the adv(4), adw(4), aha(4), ahb(4), aic(4), 
and bt(4) drivers so that they no longer use Giant.  I would appreciate any 
testing folks are able to do.  The patches are against HEAD but should apply 
to 8 or 9.  Make sure you have INVARIANTS and INVARIANT_SUPPORT enabled for 
any initial testing that you do.  Thanks!
